MAC address than in the router’s ARP table, it will send an answer with
the correct MAC address.
®
Such request is sent by the PCs working under the Microsoft
Windows™ operating system during the boot-up. If the ARP reply from
the router comes, the PC will show a message that this address is
occupied, which will make an illegal use of that IP address impossible.
The “strictarp” mode may be disabled using
“strictarp off”.
3.3.26. syslog
The router may send the messages about its status and important
events to a syslog server. To configure syslog logging following
commands may be used:
¡
syslog on - enables logging
¡
syslog off - disables logging
¡
syslog host <IP address> - sets the IP address to which the
messages will be sent
3.3.27. telnet
The command allows limiting the telnet access to the router. The
access may be enabled or disabled by entering “ telnet on” or “ telnet
off ”, respectively.
Moreover the access may be limited to a certain IP address:
telnet host <IP address>
If the IP address is set as 0.0.0.0, then the access is possible from
anywhere in the network.
3.3.28. tftp
The command configures the TFTP server used for the firmware
upgrade. Three options are possible:
¡
tftp on - enables the TFTP server
¡
tftp off - disables the TFTP server
¡
tftp host <IP address> - if the server is enabled, the access to
it may be limited to a certain IP address. If this address is set to
0.0.0.0, then the access isn’t limited.
21
3.3.29. timeout
The command sets the inactivity time (in seconds), after which
the telnet connection is closed. It has following syntax:
timeout <during the session> [<during logging in>]
The first parameter is used after the logging in and the second
one (optional) during the log-in. Entering “0” disables the timer.
These settings are also applied to the serial console if its access is
password protected (using the „console passwd on” command).
3.3.30. uptime, w
Shows the time elapsed since the router booting.
3.3.31. user
The “user” command is used to manage users having access to
the router. The router may work in two different modes:
¡
single user - only the password is necessary to access the router.
The user that logs in has the full access to the device.
¡
multiple users - allows creating many users with different
names, passwords and access levels
The “user” command has following syntax:
¡
user list - shows the user list
¡
user add <name> - adds a new user
¡
user del <name> - removes an user
¡
user passwd <name> <password> - changes the user’s
password
¡
user level <name> <access level> - changes the user’s
access level. The <access level> parameter may be one of:
§
admin - full access to the device
§
read-only - permits only reading of the configuration and the
statistics
¡
user mode { single | multi } - selects the working mode - to
either single or multi-user
3.3.32. ver
